1. Everyday Math Lesson 3.6 - Grade 4 World Tour: Flying to Africa

2. Using your Student Reference Book Open to the Country Profiles in your student reference book on pages 279- 281. You will be looking up information about Cairo, Egypt and recording this information on your Country Notes pages in the back of your workbook. You will also be recording your progress on a Route Map on pages 172-3 of your workbook. Locate those pages now.

3. Name the 7 continents North America, South America, Europe, Africa, Asia, Australia and Antarctica. Note that in your Student Reference Book that Australia was combined with Asia and Antarctica is not listed, for a total of 5 regions.

4. Complete the Route Turn to the Route map page in your workbook on page 172-3. Draw a direct route from Washington D.C. to Cairo Egypt; put an arrowhead at the destination (Cairo, Egypt) Record information that you find out about Cairo (Using the reference book) on page 174-5 of your workbook. Be sure to include today’s date.

5. Route Log Now, locate the Route Log on page 171 of your workbook. Fill in today’s date. Then, for item 1 print USA under country, then Washington D.C. for it’s capital. For item 2 write Egypt for country, then Cairo for the capital. We will find and fill out the Air distance in the next lesson.

6. Elapsed Time There are a few methods to learning how to solve Elapsed Time problems. Work with me as I show you a few examples from your workbook. (This is pages 63A and 63B of your workbook)

7. Elapsed Time Suppose you are flying from Charleston, South Carolina, to London, England. You have a connecting flight in Washington, D.C. 1. Your flight to Washington D.C. leaves Charleston at 7:05 a.m. It lands in Washington at 8:34 am. How long was the flight? How would you figure this problem out?

8. Elapsed Time In this case you might say that there is one hour difference between 7 and 8, so it is one hour… and there are 29 minutes between 7:05 and 8:34 so that is 29 minutes. So the answer must be one hour and 29 minutes. 8:34 – 7:05 = 1:29 or 8-7 = 1 and 34 – 05 = 29 You would be right, but what happens if the numbers don’t subtract so nicely?

9. You could also do it this way… 7:05 8:05 8:34 1 hour 29 minutes

10. Elapsed Time Your flight from Washington D.C. to London is scheduled to leave at 12:02p.m. The flight time is 7 hours and 19 minutes. At what time does it arrive in London (D.C. time?) 12:02 + 7:19 = 12 + 7=19 Yes, but there is no 19 on the clock! Ok.. So count on.. From 12…then..1….2….3…4…5…6…7 (So 7 o’clock! P.M. ) 2 + 19 = 21 minutes The answer is 7:21 P.M

11. Elapsed Time There is a 5 hour time difference between Washington D.C. and London. What time is it in London when you land? 7:21 pm + 5 hours. 7 + 5 = 12 The minutes stay the same! 12:21 A.M.

12. Elapsed Time Your return flight from London arrives in Washington D.C. at 4:46p.m. Your flight to Charleston is scheduled to leave Washington D.C. 3 hours and 12 minutes later. What time does your flight to Charleston leave? Lets see…. 4:46 p.m. + 3:12 4 + 3 = 7 46 + 12 = 58 we are still in p.m. so the answer is 7:58p.m.

13. Elapsed Time Your flight to Charleston is delayed because of stormy weather. It finally leaves at 8:57p.m. and lands in Charleston 1 hour and 44 minutes later. What time does it land in Charleston? 8:57 + 1:44 = 8+1 = 9 57+44 = 101 Hmm… there is no 9 hours and 101 minutes… What do I do now?

14. Lets try Elapsed Time again. 8:57 + 1:44 = So…. Minutes first this time.. 57 + 44 = 101 There are 60 minutes in an hour so 101 minutes becomes 101-60= 41 SO 1 hour and 41 minutes. 8 + 1 = 9 9 hours + 1 hour and 41 minutes = 10 hours and 41 minutes or 10:41p.m.

15. Can I show you another way to do that problem? 8:57 p.m. Flight leaves 9p.m. 10p.m. 11p.m. 3 minutes And takes 1 hour and 44 minutes to get there… 1 hour 44-3 minutes = 41 minutes I used 3 minutes before 9 pm, so I subtracted those from my total minutes to see how many I had left. I am in the 10 th hour and have 41 minutes left, so I must land at 10:41 p.m.!

16. Now you try… Complete the problems on page 63B in your workbooks. When you are done, turn to the next page and check your answers. If your answers do not match the ones I have down, then re-check your work.

17. Answers 63B 6. 4:56 p.m. 7. 9 hours, 22 minutes 8. 9:40 a.m. How’d you do?

18. Homework Please complete page 87 – Number Stories about Egypt as homework

19. Games You may play in class (with a partner) or you may borrow and take home Seega. Seega is a traditional Egyptian game popular among young Egyptians today. Players use strategic moves to transfer three counters on a game board to a new straight line.
